Answer:
because of the nature of his deeds.
Step-by-step explanation:
In 'Oedipus Rex' it is possible for Oedipus to be both guilty and innocent at the same time because of the nature of his deeds. Oedipus truly loved his people as a king and when he ventured out to find the killer of King Laius, an unexpected turn of events took place.
In the attempt to find the killer, he discovered that he was the one who killed his father, Kind Laius. However, he did not know that it was his own father whom he killed when he was young. Therefore, he can be seen as innocent.
At the same time, Oedipus is also guilty because nevertheless he killed another person who unfortunately happened to be his own father.
